A brain-computer interface for controlling an exoskeleton
Scientists working at Korea University, Korea, and TU Berlin, Germany have developed a brain-computer control interface for a lower limb exoskeleton by decoding specific signals from within the user’s brain. Using an electroencephalogram (EEG) cap, the system allows users to move forwards, turn left and right, sit and stand simply by staring at one of […]

Study finds geoengineering technique would not stop sea level rise
By Matt Carroll, Penn State University UNIVERSITY PARK, Pa. — Albedo modification, an emerging technology with the potential to offset some aspects of climate change, shouldn’t be counted on as a short-term solution to stop rising global sea levels, according to a new study from Penn State geoscientists. “In the short term, the first few […]

Chocolate physics: how modelling could improve ‘mouthfeel’
Lecithin is an ingredient that you’ve probably never heard of, but one that plays a vital role in the production of chocolate and many other foods. It’s never been clear how this ingredient works on a molecular level, and confectioners have relied on observational methods – essentially trial and error – to perfect their recipes. […]

In September’s Physics World: The secret life of scientific ideas…
Many of the most memorable stories in the history of science revolve around the conscious realization of an idea – the “Eureka!” moment. But what triggers these moments? Is there always some serendipitous event preceding a sudden epiphany, such as when Isaac Newton famously figured out gravity when he saw a falling apple? Writing in […]

Replicating liver cells for fast drug testing
Schematic of the assembled 3D construct device Aleksander Skardal et al 2015 Biofabrication 7 031001 Scientists have developed a new technique that produces a user friendly, low cost, tissue-engineered pseudo-organ. The chip-based model produces a faithful mimic of the in vivo liver inside a scalable fluid-handling device, demonstrating proof of principle for toxicology tests and […]
